PSLV-C41/IRNSS-1I

India's Polar Satellite Launch Vehicle, in its forty-third flight (PSLV-C41) in XL configuration will launch IRNSS-1I Satellite from First Launch Pad (FLP) of SDSC SHAR, Sriharikota. The 'XL' configuration of PSLV is used for the twentieth time. The IRNSS-1I is the eighth satellite to join the NavIC navigation satellite constellation.

PSLV-C41/IRNSS-1I Mission is scheduled to be launched on Thursday morning, April 12, 2018 at 04:04 Hrs (IST).

IRNSS-1I

IRNSS-1I is the eighth navigation satellite to join the IRNSS space segment. Its predecessors, IRNSS-1A, 1B, 1C, 1D, 1E, 1F and 1G were launched by PSLV-C22, PSLV-C24, PSLV-C26, PSLV-C27, PSLV-C31, PSLV-C32 and PSLV-C33 in July 2013, April 2014, October 2014, March 2015, January 2016, March 2016 and April 2016 respectively. Like all other IRNSS satellites, IRNSS-1I also has a lift-off mass of 1425 kg. The configuration of IRNSS-1I is similar to IRNSS-1A, 1B, 1C, 1D, 1E, 1F and 1G.

Payloads: Like its other IRNSS predecessors, IRNSS-1I also carries two types of payloads – navigation payload and ranging payload. The navigation payload of IRNSS-1I transmits signals for the determination of position, velocity and time. This payload is operating in L5-band and S-band. Rubidium atomic clocks are part of the navigation payload of the satellite. The ranging payload of IRNSS-1I consists of a C-band transponder, which facilitates accurate determination of the range of the satellite. It also carries Corner Cube Retro Reflectors for LASER Ranging.

IRNSS-1I will be launched by PSLV-C41 on Thursday morning, April 12, 2018 at 04:04 Hrs (IST) from SDSC SHAR, Sriharikota.

Do you have interest in Satellites? It is good to see so many positive threads from your side about ISRO and DRDO.

Of course. I've been fortunate enough to see some of their work directly and meet some of the big names, although the most time I've spent is in India's Basic Science labs.

PSLV-C41 Successfully Launches IRNSS-1I Navigation Satellite
In its forty third flight, ISRO’s Polar Satellite Launch Vehicle PSLV-C41 successfully launched the 1425 kg IRNSS-1I Navigation Satellite today (April 12, 2018) from Satish Dhawan Space Centre SHAR, Sriharikota.
PSLV-C41 lifted off at 0404 hrs (4:04 am) IST, as planned, from the First Launch Pad. After a flight lasting about 19 minutes, the vehicle achieved a Sub Geosynchronous Transfer Orbit with a perigee (nearest point to earth) of 281.5 km and an apogee (farthest point to earth) of 20,730 km inclined at an angle of 19.2 degree to the equator following which IRNSS-1I separated from PSLV.
After separation, the solar panels of IRNSS-1I were deployed automatically. ISRO's Master Control Facility (MCF) at Hassan, Karnataka took over the control of the satellite. In the coming days, orbit manoeuvres will be performed from MCF to position the satellite at 55 deg East longitude in the planned Geosynchronous Orbit with an inclination of 29 deg to the equator.
IRNSS-1I is the latest member of the ‘Navigation with Indian Constellation (NavIC)’ system. NavIC, also known as Indian Regional Navigation Satellite System (IRNSS), is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland.
A number of ground facilities responsible for IRNSS satellite ranging and monitoring, generation and transmission of navigation parameters, satellite control, network timing, etc., have been established in many locations across the country as part of NavIC.
Till now, PSLV has successfully launched 52 Indian satellites and 237 customer satellites from abroad.
